# 8. Show the descending order of weights of the students?

From the information given**, we know that**:

**Ahmad weighs thrice as much as Ali****Ali weighs 5 times as much as Akbar****Akbar weighs half as much as Nasir****Nasir weighs half as much as Shehbaz**

Let’s use some algebra to solve for the weights of the students in terms of Akbar’s weight, which we will represent by the variable “a”.

**Ali weighs 5 times as much as Akbar, so Ali’s weight is 5a.****Ahmad weighs thrice as much as Ali, so Ahmad’s weight is 3(5a) = 15a.****Nasir weighs twice as much as Akbar, so Nasir’s weight is 2a.****Shehbaz weighs twice as much as Nasir, so Shehbaz’s weight is 2(2a) = 4a.**

**Therefore, the descending order of weights of the students is:**

**Ahmad (15a)****Shehbaz (4a)****Nasir (2a)****Ali (5a)****Akbar (a)**

Note that we cannot determine the actual weight of any student without knowing the weight of Akbar, but we can compare the relative weights of the students.
